Unified SD-WAN & SASE for Construction Sites
Reliable, high-speed connectivity for hard-to-reach sites, temporary projects, and complex joint ventures — with secure, cloud-delivered access built in as your sites and supply chain grow.
Trusted by the UK's largest construction firms to connect major infrastructure projects using Ethernet, FTTP, LEO Satellite, 4G, and 5G.
Connect hard-to-reach sites with unified SD-WAN for construction
Using a blended mix of Ethernet, FTTP, LEO Satellite, 4G, and 5G, we connect multiple, temporary, and hard-to-reach building sites. We have a depth of experience working with the UK's largest construction companies and are relied upon to support some of the UK's largest infrastructure projects. Our unified SD-WAN solution bonds these connections for maximum uptime and performance.
Seamless network integration for joint ventures for construction
Construction is full of joint ventures (JVs), creating complex network challenges. We have proven experience bridging disparate networks, such as legacy MPLS and modern SD-WAN, to ensure seamless and secure collaboration between partners. Increasingly, this is delivered through Zero Trust principles - the same approach that underpins Secure Access Service Edge (SASE), so each partner gets access to exactly what they need, and nothing more. We currently provide this critical network integration for our top-tier construction customers.
Compliant connectivity for critical national infrastructure
We are relied upon to provide critical connectivity for the UK's Critical National Infrastructure (CNI) projects. We work directly with authorities, local, and central government to engineer effective, secure, and compliant solutions that meet the stringent regulatory requirements for nationally significant projects. Cloud-delivered security controls, including Zero Trust Network Access (ZTNA), help satisfy the strict access-control standards CNI projects demand — verifying every user and device before granting access, rather than trusting anyone inside the network perimeter by default.
Secure, Cloud-Delivered Access for Every Site and Subcontractor
SD-WAN solves the connectivity problem on construction sites getting a fast, resilient network up in days rather than weeks. But connectivity alone isn't security. As more subcontractors, JV partners, and remote project teams need access to your systems from sites with no fixed perimeter, the network itself becomes the attack surface.
That's where Secure Access Service Edge (SASE) comes in. SASE combines SD-WAN with cloud-delivered security - Zero Trust Network Access (ZTNA), secure web gateways, and consistent policy enforcement - so every user, device, and site connects through the same verified, least-privilege model, wherever they're working from.
For construction organisations, that means:
- Temporary sites secured from day one - new site offices inherit your security policy automatically, with no manual firewall configuration.
- Subcontractors and JV partners access only what they need - ZTNA replaces broad network access with granular, identity-based permissions, reducing the risk one partner's breach becomes everyone's problem.
- Remote project teams stay protected - site managers, surveyors, and design teams working from vehicles, cabins, or client offices get the same security posture as HQ.
- One policy, every location - rather than managing security separately at each site, SASE lets you set it once and apply it everywhere.
Claranet is an accredited Fortinet SASE specialist, building this directly on top of the SD-WAN foundation already protecting your sites.
Key Benefits
-
Zero Trust access for every site
ZTNA verifies every user and device before granting access, regardless of location.
-
Consistent security policy everywhere
SASE applies one policy across HQ, site offices, and JV partners, cutting configuration drift.
-
Safer subcontractor access
CASB-style visibility and control over who touches your cloud systems, without slowing down onboarding.
-
Web threats blocked at the source
Cloud-delivered secure web gateway (SWG) filtering protects users even on unmanaged site connections.
-
Operational resilience by design
Combining SD-WAN's connectivity resilience with SASE's security resilience reduces single points of failure.
-
Hybrid working, secured
Site-based, office-based, and remote project staff all get the same protection, wherever they log in.

Connectivity & SD‑WAN Faqs for construction
-
SASE is a cloud-delivered architecture that combines SD-WAN connectivity with security functions like ZTNA and secure web gateways, applying one consistent policy to every user and site.
-
SD-WAN handles how traffic moves; SASE adds how that traffic and the people using it gets verified and protected, without needing separate hardware at every site.
-
Construction's temporary sites, shifting workforces, and multi-party JVs create constantly changing access needs that traditional perimeter security can't keep up with.
-
New sites inherit existing security policy automatically through the cloud, so there's no manual firewall setup each time a site opens or closes.
-
It's a technology that fuses multiple internet connections (like 5G, LEO satellite, and fixed-line Ethernet) into a single, ultra-reliable link. If one connection fails, traffic instantly moves to the others with no downtime, which is essential for a busy site office.
-
We use 'day zero' connectivity. We ship a pre-configured SD-WAN router with 4G/5G capabilities. You plug it in, and it's online in minutes. This provides an immediate, secure corporate connection while we manage the installation of fixed-line services like Ethernet or FTTP in the background.
-
LEO (Low Earth Orbit) satellite provides high-speed, low-latency internet, unlike old satellite technology. It's perfect for construction sites in remote or new-build areas where fixed lines don't exist yet. It's a game-changer for providing reliable site connectivity for applications like video conferencing and cloud data access.
-
We use secure SD-WAN and next-gen firewalls to create secure tunnels between the JV partners' networks. This allows teams to collaborate and access shared systems while keeping each company's corporate network secure and separate, applying "least-privilege" access policies. This is the same Zero Trust model that underpins Secure Access Service Edge (SASE) - every user and device is verified before access is granted, regardless of which partner network they're connecting from.
-
We have extensive experience providing secure, resilient connectivity for Critical National Infrastructure (CNI) projects. This involves designing networks that meet specific government security standards, ensuring high availability, and working with local authorities and central government to ensure all solutions are compliant.
